Check if Process is running
Hi ,

I have a csh code below which check the process if it's running.
Can any expert advise me on the following:
1) what does this notationmean ">!" and how is it different from the append ">" notation ?
2) how does "setenv" work in this code ?


Code:
# Check whether there is a running process else quit script
ps -ef | grep moniter_11thDec | grep "bin" | grep -v "grep" >! $TEMP/temp_file.txt
setenv PROCS `cat $TEMP/temp_file.txt | wc -l`
if ($PROCS > 1) exit 1

1. Force redirection even if noclobber is set
2. Equivalent to set/export sequence

Can you help me convert as i am still a novice in Perl ?
